DETACI-IABLE HANDLE "FOR CUTTERS, &c.

Application led March 15, 1918.

if 'o all 'Lo kom t may concern:

Be it known that I, Richiami F. COLLINS, a citizen -of the United States, and a resident of Norwood, county of Delaware, State of Pennsylvania, have invented certain Improvements in Detachable Handles for Cutters, &c., of which the following is a speciiication.

rlhe object of my invention is to provide means for holding a cutter used for metal working and to provide a detachable handle, which will rigidly hold the cutter' and which can be readily detached or applied.

In the accompanying drawings:

Figure l is a perspective view of my improved handle, showing it applied to the cutter Fig. 2 is a side view, partly in section;

Fig. 3 is a plan view, partly in section;

Fig. l is a perspective view of the hinged strap by which the handle is secured to the critter;

Fig. 5 is a detached perspective view of a plate with the reinforcing spindle for the handle;

Fig. 6 is a perspective view of one form of cutter; and

i Fig. 7 is a view illustrating a modifica tion of the invention.

l is the cutter which, in the present inn stance, is rectangular in cross section and has a sharp edge 2 and is for the purpose of cutting the metal in steel and iron mills and foundries. The fiat surface of the cutter is used as a head against which a sledge strikes. The handle 6 is for the purpose of allowing one man to hold the cutter while another strikes a blow with a Sledge. The usual method of making these cutters is to form an eye in the center through which the handle extends. This weakens the cutter to such an extent that it often breaks at the eye so that the tool has to be disu carded.

By my invenion, I form an annular recess 3 at the center of the cutter, leaving the body portion solid so as to resist the blows. I provide a strap it of a thickness, in the present instance, equal to the depth of the recess 3 and this strap engagesl the cutter on three sides, as clearly shown in Fig. 3. The strap is made in two parts and is connected together at the front by a hinge 5 so that it can be opened, as clearly shown in Fig. Lf. The strap is turned in, as at 7, so as to form shoulders at the back Specification of Letters Patent.

of the cutter, and located between the shoulders 7 and the cutter isa plate 8, which snugly fits the recess at the back of the cutter and has a spindle 9, which extends into the handle 6. This spindle not only holds the plate, but also reinforces the handle. The strap l has extensions l0, which are curved, as shown, to fit the handle 6 and in each extension is a slot ll for the reception of a transverse bolt l2, which .passes through an opening 13 in the handle and through an opening 14 in the spindle 9, and is provided at its opposite end with a wing nut l5. l/Vashers are used between the head of the bolt and one extension of the strap and a washer is also used between the wing nut 15 and the other extension. In the present instance, the bolt snugly fits the opening in the handle and in the spindle 9 andis adjustable in the slots of the extension so that in applying the handle to the cutter, it is pushed against the cutter until the plate 8 is in contact with the cutter,

then the strap is secured to the handle by a transverse bolt l2.

In some instances, the plate 8 and spindle 9 may be omitted, as shown in Fig. 7, and in this instance the end of the handle 6a is brought in contact with the side of the cutter and the inturned flanges 7a rest directly against the back of the cutter. In this particular instance, the recess in the cutter only extends at the front and each side. This adds strength to the cutter, las the back is not recessed.

I preferably so design the strap that the diameter of the space between the extensions is greater than the diameter of the handle, so that when the nut is turned to bring the extensions onto the handle, the strap is also firmly clamped to the cutter.

In assembling the tool, the strap 4 is placed on the cutter' and the handle, with the plate placed in the recess at the back of the cutter and forced against the cutter. The bolt is passed through the several openings and then clamped tightly, making a firm connection between the handle and the cutter.

While I have illustrated my invention as applied to a particular form of cutter, it will be understood that the shape of the cutter will vary according to the use for which it is intended and though it is particularly adapted for holding cutters, it can be used for holding hammer heads, picks,

and like objects to which a handle is secured.

I claim:

lpThe combination of va cutter, said cutter being recessed on a plurality of its sides; a strap made in two sections and adapted to enter said recesses; said sections having rearward extensions shaped to conform to a handle; inturned earson the strap bearing against the back ot' theV cutter; a handle extending between the extensions and adapted to be engaged thereby; and means extending through the handle and through the extension adapted to clamp the extensions to the handle.

2. The combination of a cutter having a recess on all four sides; a two-part strap shaped to lit the recess, the two parts oi' the strap being connected together by hinges at the front, each. section of the strap having` an extension; a handle located between the extensions, said extensions being shaped to lit the handle; a transverse holt for securing the extensions to the handle; and inturned flanges on the strap located at the back'of the cutter.

3. rlhe combination of a cutter having a recess extending on all four sides thereof; a handle; a longitudinal opening in the handle; a plateV at the end of the handle having a spindle adapted to the opening in the handle, the plate extending into the recess in the rear of the cutter; a transverse opening in the handle and in the spindle; a strap locatedV in the recess in three sides of the cutter, said strap having extensions shaped to conform to the shape of the handle7 said extensions being slotted; a bolt extending through the slots in the extensions and through openings in the handle and the spindle; and a nut on the bolt for drawing the extensions tightly on the handlel and against the sides of the cutter.

In witness whereof l ailix my signature.

RICHARD P. COLLINS.
